Answer:
Step-by-step explanation:
We would assume a binomial distribution for the handedness of the population. Let x be a random variable representing the type of handedness in the population. The probability of success, p is that a randomly chosen person is left handed only. Then probability of failure is that a chosen person is not left handed only(right handed only or both).
p = 12/100 = 0.12
number of success, x = 20
n = 200
the probability that there are at least 20 left-handers is expressed as P(x ≥ 20)
From the binomial probability calculator,
P(x ≥ 20) = 0.84
Answer:
-5/9
Step-by-step explanation:
−4/5 divided by 12
/5
=-20/36
simplify
=-5/9
Answer:
y=5/6 x+5
Step-by-step explanation:
First look at the y axis, you'll see that the line passes 5 which is B. Then use Rise/Run (5/6) to find points to find M
then plug it in the equation y=mx+b
Answer:no it is not
Step-by-step explanation:
28 squared + 62 squared does not equal 75 squared
